Abengoa Solar Purchases 3,000 Acres for $1 Billion Solana Generating Plant
Abengoa Solar, a Spanish-based solar energy company, has purchased roughly 3,000 acres near Gila Bend, AZ, where it intends to develop the world's largest solar power plant.
An investment entity associated with Brandon Wolfswinkel of Tempe, AZ, sold the land for $45.12 million, or about $14,700 per acre.
Abengoa Solar, which has solar plants in Spain and northern Africa, will construct and operate the 280-megawatt, $1 billion facility known as the Solana Generating Plant. The plant will use thousands of giant mirrors covering 1,900 acres to harness the sun's heat (rather than its light) to turn steam turbines, generating electricity.
The plant is scheduled to go into production in 2011. It will be able to power 70,000 households while avoiding more than 400,000 tons of greenhouse gas emissions, according to Abengoa.
Arizona Public Service, the state's largest utility, has agreed to purchase the energy from Abengoa over the next 30 years. "This is a major milestone for Arizona in our efforts to increase the amount of renewable energy available in the United States," stated Arizona Governor Janet Napolitano. "Arizona is leading the way in protecting our world for future generations through increasing the amount of renewable energy, combating climate change, fighting for air quality and much more. This plant will offer Arizonans a clean and efficient source of energy."
Very tired, cold, mean ones?
I don't think they plan to use fixed panels. With movable panels, they will be able to track the sun as the Earth rotates, giving a longer maximum power. Also, some energy will be stored as heat, perhaps from the midday maximum, to be used later in the evening.
It is trivilally simple to provide more reflection surface than is required for maximum collection efficiency, but it makes sense to do so to extend the productivity time. Excess or unneeded panels can be cycled through maintenance procedures when they are not immediately required for energy production.
With a short shelf life.
It is only about 50 miles as the crow flies from Gila Bend to Phoenix, Arizona- I guess that is the intended power demand.
More later.
> A kilowatt is one thousand watts, (or a billion watts)
Where did you get a billion from, a kilowatt = 1000 watts.
> 4,00 Billion = 4 Trillion
4,000 Billion = 4 Trillion
> 40,000 Million = 4 Trillion (4,000,000,000,000)
40,000 Million = 40 Billion (40,000,000,000)
> 280 megawatts = .28 Kilowatts
280 megawatts = 280,000 Kilowatts
Now see post #63 for the correct analysis of space needed. I know a lot of good conservatives are skeptical about anything green (for good reasons) but this is actually very feasible assuming the costs work out (looks like 10-15 year payoff). However I do question why they paid $14K+ per acre bought, that seems awfully high for Arizona desert, so I do question some of their business sense.
?
125.00 - 175.00 a month from May through Sept is what southerners pay NOW for electricity.
Figure about 50.00 - 75.00 month the rest of the year, IF they have gas heat and a gas water heater. Otherwise, every month’s bill is higher.
Only if you're not the one feeding him...
It’s almost time to update “The Man With The Golden Gun” — some new super-duper technique to concentrate energy from the sun while Britt Eklund’s successor prances about in a bikini......
Pictures. We want pictures.
Ooooooooooo, Power porn...

Wow! You have a probelm for every solution!
Your numbers are off for AZ. $200 is an average bill here.
Heat loss and molten metal flow resistance losses through the miles of small bore piping between the collectors and the central “boiler” is not going to be pretty. Probably solvable, but not cheaply or efficiently solvable. Maintenance and replacement of this extremely complex heat-transfer system is going to add to year-year costs NOT in the advertisements by the AGQ extremists pushing this idea. This solar heaters have been built before (Mojave and south France). And never succeeded before either.
Their power is already 40% higher than conventional, and extends only from morning (after pipes heat up) to sunset + 6 hours - so there is NO justification without (artificial, assumed, socialist-promoted) greenhouse gas price drivers.
Thank you. I don’t live in Arizona, but I had a rough idea about what monthly electricity bills run there.
Assuming that power can actually be sent that far anyway: transmission losses limit electric power to 500 miles (best) to no more than 900 miles. Doesn’t rule out southern plants in “clearer” states to feed the northern cloudy states, but you need to then multiply by another 4 to 8 factor because of cloud cover and rain and snow outside of the benign deserts.
Good thing is the desert location here, and the stored production. But, for every hour used from stored energy at night/early evening each day, you lose 1 hour gaining that energy the next morning. Cycling the “boiler” as it cools each evening kills steel and piping: we may be lucky for this to run 10-12 years without fatigue failure, rather than 25-40 years for a constantly on thermal plant not undergoing 365 heatup cycles a year.
I would gladly sell my prime desert solar land for $14,700 an acre. Then I would buy some nice land in Alaska for $3000 an acre and retire.
Because they will not use much water?
I'm glad it's Arizona Public Service doing it, and not my power company which is Salt River Project. We have much better rates, so much so that living in an APS neighborhood will knock thousands of dollars off the value of your house. Savvy home-buyers have this question at the top of their list of things to ask a Realtor. I won't even look at a house served by APS becaused the electricity bill is consistently more than 15% higher.
